Is My Thinking Reasonable: A's Impact on Oscillator Motion

AI Thread Summary
A is identified as the primary factor influencing the amplitude of motion in an oscillator at resonance, while B, C, and D are fixed or dependent variables. Understanding the physics behind oscillators is crucial to grasp why A is the correct answer. The damping force, which is a characteristic of the oscillator, also plays a role in the overall motion. The discussion emphasizes the importance of analyzing these relationships to clarify the impact of A. Ultimately, the reasoning aligns with fundamental principles of oscillatory motion.

Homework Statement
A sinusoidal force with a given amplitude is applied to an oscillator. At resonance the amplitude of the oscillation is limited by:
A. the damping force
B. the initial amplitude
C. the initial velocity
D. the force of gravity
E. none of the above

The answer is A
Relevant Equations
F = -kx
I just want to check if my thinking is reasonable. Since B,C and D are all dependent or fixed by the oscillator, A is the only factor to affect the amplitude of the motion at resonance or even throughout the entire process?
 
Physics news on Phys.org
I think it would be better to know why the answer is A.
 
The damping force is also generally a property of the oscillator.

In order to deduce why A is the correct answer, you need to consider the actual physics of the oscillator.
 
Thank you all. I got it.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
